Is Roger really that ignorant?
Air compressors have cooling fins.
A bicycle pump heats up when one fills the tire.
Smarten up Rog. If that is possible.
And yet CO2 and every other welding gas I have ever used, such as Oxygen, Acetylene, and Argon are colder than ambient when released from compression in a tank. Our CO 2 regulators on the MIG welders would frost up when using a high flow on hot humid days.
Hydrogen heats up due to its negative JT coefficient at ambient conditions.
MIG and TIG (Heliarc) welders uses gases like CO2 and Ar as shielding to block Nitrogen and Hydrogen to prevent oxidation and cracking of the metal during the welding process. In MIG and TIG welding they provide for the same type of microenvironment around the arc as the flux on Arc welding rods.
In the MIG welding of heavy carbon steel plate both shielding gases and flux core or flux shield welding “wire” is used. You haven’t lived until you’ve done long continuous fillet welds requiring multiple passes in full welding leathers on a hot day using a spray transfer system running 3/32″ flux shield wire at 1,400 amps and C25 (25% CO2 and 75% Ar) gas. Can’t use a fan to keep yourself cool because it will blow away the gas.
I guess that’s one reason why good welders are paid well and in high demand.
I’m making better money driving a big truck than the top welder and fabricator at my families steel service center and fabrication business. It’s a business that was started the year I was born and employs over 40 people. But that’s a nonunion shop. I grew up working in it and that’s where I learned the steel fabrication and welding trades. But the really heavy plate welding as described was what I did for the now defunct Insley Manufacturing company that made cranes and backhoes.
Now at home I am pretending to be a finish carpenter. Just finished putting solid oak crown molding and trimming out a doubled hung and medium sized bay window in our dining room. Installation of solid hard wood trim in an older home (this part built in 1943) takes the patience of a saint. Corners aren’t square and straight lines are no longer straight. And a mistake is expensive. A 12′ long piece of prefinished golden oak trim for the widows costs $40.00. I can’t imagine how labor intensive and tedious such work was before nail guns and compound miter saws with laser lines back in the day when the oak floor and base board was put into this house. So next it’s on to sanding the floor and base boards and redoing the finish on them.
Then I’ll play electrician installing a new ceiling fan a lighting unit.
Then I will become a cabinet maker adapting a solid oak corner nook bench set by adding storage under benches.
Then I will become a upholstering apprentice working with my neighbor who has a shop. He is giving me the material to make the covering cushions for the seats. The foam padding will come from king size bed pads the Indianapolis Colts used when they did their preseason practices as Anderson University. So we’ll be sitting on padding that Peyton Manning may have slept on covered in a deep burgundy Naugahyde. . Also upholstering the seats to the oak chairs and a window seat cushion for the bay window with the same material.
When it’s all said and done I’ll have about $3,000. 00 in redoing a 12′ x 9 1/2′ dining room and 4 1/2′ wide by 8′ long entry alcove. That includes the corner nook table and benches. If I had professionals do it I would have had $10,000 in it easy.
It goes both ways i think.
Increased pressure inside a scuba tank should not have a different temperature than one with less pressure in the long run.
But the process during increasing will show different results between a full scuba tank and one that gets filled by only 10%.
Also the full scuba tank should store heat longer than the empty one.
imo it depends on wether the process is static and isolated or not.
But someone should ask Roger why the hell stupid stupid egineers are using supercomplex and expensive systems to protect space shuttles for when they reenter atmosphere and the massive pressure is creating enourmous heat :)
Oh, my God. These people are cement-headed. They’re out of control. I can’t believe I just read something that said “increasing pressure does not increase temperature.” This climate change garbage has gone way too far. These mental cases are denying basic science.
PV=nRT
Avogadro’s Law

In this instance, Gay-lussac’s law is what you are looking for.
https://en.m.wikipedia.org/wiki/Gay-Lussac's_law
The increase in temperature as you go lower in the atmosphere comes from static gravitational compression of that atmosphere, as predicted by the ideal gas law itself.
The low altitude molecules have decreased mean free path, higher collision rate, thus increased temperature is measured.
Maybe Roger Clague’s first language isn’t English.
Yes, he’s from the UK apparently and has a degree in chemistry (?). That’s hard to believe.
Something happened to him over the years to have lost what he most certainly had to have known.
I think he will appreciate:

1834…so a bit older than evolutionary denialism…interesting.
Nobody here is denying that the climate changes. We just believe that it takes an arrogant fool or crook to claim that us puny humans are having the massive effect on global climate that is being claimed. And besides, the hypothesis of AGW has already been falsified. The models require persistent hot spot(s) in the upper troposphere of the tropics and they have not appeared. The whole claim is based on runaway feedback of forcings like never have ever before occurred in the history of this planet since it’s had an atmosphere. And besides, any person that hasn’t just fallen off the turnip truck knows that when politicians start telling you that they need to take control of an ever increasing amount of the economy and reduce personal liberties to protect us, you better be very skeptical.
RAH you don’t seem to understand that agriculture, urbanisation and the industrial revolution have profoundly changed land use and the composition of the atmosphere. What makes you think these “puny” changes can not have profound effects on the climate?
Because they haven’t on a global scale. Sure there are problems like UHI effect but they are more local. CO2 is not the control knob of our climate and never has been. The warming that has occurred is well within the parameters of natural variation as are SL changes, and ice levels at the poles. I am far more concerned getting some kind of system up to detect and prevent a hit by a big chunk of ice or rock from space than the beneficial CO2 level we have now. With just money that is being wasted on this climate change and “Green energy” crap could have been used to fund the research and programs to address a whole lot of other much more clear and present real threats to humanity.
This may give you a perspective how puny we are.

Yes LAND USE changes does have an effect, but is a small one and local.
You overrate the trace puny molecule with a puny IR absorption range.
@terak …
Oh puleeez. All of the agriculture and “urbanisation” in the world accounts for less than 2% of the Earth’s surface.
This is as dumb as the idiots that believe painting their roads white is going to have an effect on global temperatures. Meanwhile, the surface area of all of the roads in the entire world doesn’t even equate to 0.0001% of the world’s surface area.
Humans actually occupy a very small portion of the Earth’s surface. Human agriculture and “urbanisation” is completely dwarfed by mother nature. You could not even measure the human effect on a global scale.
Better to remain silent and be thought a fool than to speak out and remove all doubt.
YAWN.. you are a PATHETIC idiot, terak
A minor, zero-science, insignificant troll.
He or it, whatever terak is, seems to deny the existence of refrigeration.
Climate history shows that the world is very much in a cold part of the current interglacial, just a small bump out of the LIA
THANKFULLY, warmed slightly out of that coldest period in 10,000 years.
It is actually the AGW-suck0-phants that are the CLIMATE CHANGE DENIERS
Roger’s tweet must be a hoax.
No one could possibly be that bloody stupid.
Just as Joe Bastardi said, the subtropical storm now named Alberto is gaining strength quickly due to feedback as it nears shore. 65 mph winds and increasing pressure 991 mb and dropping. May not be a hurricane when it comes ashore but it sure will be close to a CAT I.
Rah, don’t you mean decreasing pressure ?? … storms decrease in pressure as they gain strength. For this is exactly what gives them strength to begin with (pressure differential).
FYI, 991mb is below ambient pressure at sea level (ie: 1000mb (or 1b) is ambient pressure at sea level).
Yes I meant decreasing pressure. Thanks for pointing that out.
Pressures vary over water. The atmosphere above Colder waters generally have a higher pressure than those over warmer waters. But the ability of warm coastal waters to help strengthen a storm is limited in most areas because the water is shallow.
Well the can name her Tropical Storm Stormy. It may turn out to be a tempest in a D cup.
@ RAH – from your comment of May 27, 2018 at 4:21 pm I can’t help wondering, have you appeared in either of the TV shows “Building Alaska” or “Tiny House Big Living”? If not, it sounds like you should!
Nope, and I know far more qualified people than I for such an appearance. My neighbor is one of them. He’s the man I go to when I’m having difficulty solving a problem or have questions.
